Description
Technical Field
[0001] The invention belongs to the technical field of substations, in particular to a water photovoltaic substation. Background Art
[0002] The floating photovoltaic substation is a substation specially used in the floating photovoltaic power generation system. Its main function is to collect, convert and distribute the electric energy generated by the floating photovoltaic array. The floating photovoltaic array is composed of a large number of photovoltaic panels, which are installed on the water surface, such as lakes, reservoirs, fish ponds, etc., and convert the absorbed solar energy into direct current. The floating photovoltaic substation is the key hub of the entire floating photovoltaic power generation system, and plays a vital role in ensuring the effective use and transmission of electric energy. The direct current generated by the floating photovoltaic array is collected by cables to the floating photovoltaic substation. In the substation, the direct current is converted into alternating current after being stepped up by the step-up transformer. Then, the alternating current is distributed to the output lines through the distribution equipment. In this process, the reactive power compensation device adjusts the reactive power according to the needs of the system, and the monitoring and communication system ensures the safe and stable operation of the substation in real time. At present, there are two main structural forms of floating photovoltaic substations: floating and fixed. The floating substation uses a floating body to float the main body of the substation on the water surface, which can adapt to changes in water levels. However, due to the complex and changeable environment on the water, when waves appear on the water surface, the platform will shake, tilt or even drift, affecting the normal operation of the equipment in the substation. In serious cases, it will cause equipment damage, short circuit and other safety accidents; the fixed substation first inserts the column pile into the bottom of the water, and then installs the substation on the platform on the column pile. Since the position of the platform is fixed, it has poor adaptability to water level changes. Summary of the invention

[0011] The beneficial effects of the present invention are as follows: 1. The present invention relates to a photovoltaic substation on water. When waves appear on the water surface, the moving waves will act on the floating body. Since the floating body is mounted on a plurality of pipe piles through a plurality of fixed columns, the floating body can be limited in the horizontal direction under the action of the plurality of pipe piles, thereby preventing the floating body from swaying back and forth in the horizontal direction when the waves act on the floating body. When the floating body is shaken by the waves, the fixed columns can only be used to move up and down along the pipe piles, thereby preventing the floating body from tilting or even drifting when it is affected by the waves. At the same time, when the liquid level increases, the floating body will drive the substation to move upward with the rise of the liquid level, thereby enabling the substation to adapt to changes in the water level and avoiding the substation being fixed in position. When the water level continues to rise, water will enter the substation.
[0012] 2. The photovoltaic substation on water described in the present invention limits the limit plate in the corresponding long groove by using a clamping plate. When there is a gap between the pipe pile and the inner circular groove of the fixed column after long-term wear, a plurality of limit plates can be used to limit the pipe pile and the fixed column, thereby preventing the floating body from driving the fixed column to collide with the pipe pile when the floating body is affected by waves, due to the gap between the circular groove of the pipe pile and the fixed column, and when the limit fixation is not performed, the pipe pile or the fixed column will be deformed and the service life will be affected. At the same time, when there is a gap between the limit plate and the long groove, the limit plate will move into the long groove and make the limit plate fit with the long groove. Subsequently, the limit plate can be fixed by the extended fixing rod and the clamping plate intersecting with the limit plate, thereby preventing the limit plate from sliding and being unable to limit and fix the fixed column, so that when the floating body drives the fixed column to move, it will collide with the pipe pile.
[0013] 3. In the water photovoltaic substation described in the present invention, since the roller rotates unidirectionally, the fixed column will no longer move downward after moving up due to the meshing of the gear teeth and the tooth grooves on the roller. Each time the waves push the floating body and the fixed column to move up, the fixed column and the floating body will be fixed after moving up. In this process, since the floating body is temporarily fixed after moving up, the impact of the waves on the floating body will be reduced when the waves flow, and the frequency of the floating body pushing the substation up and down will be reduced, thereby avoiding the floating body driving the substation up and down for a long time, which will affect the normal operation of the equipment in the substation, and in severe cases will cause equipment damage, short circuit and other safety accidents.

DETAILED DESCRIPTION
[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.
[0018] Embodiment 1: Figures 1 to 9 As shown, a water photovoltaic substation described in the present invention includes a substation 1, and the direct current generated by the water photovoltaic array is collected into the water substation 1 through cables; The substation 1 is installed on a floating body 11, and the floating body 11 drives the substation 1 to float on the water surface; The floating body 11 is disc-shaped; the floating body 11 is equipped with evenly arranged pipe piles 12, and the pipe piles 12 all pass through the floating body 11 and are slidably connected to the floating body 11; the pipe piles 12 are inserted into the soil; The floating body 11 is fixedly mounted with evenly arranged fixing columns 2; a circular groove is opened in the middle of the fixing column 2; each of the pipe piles 12 passes through the circular groove in the corresponding fixing column 2 and is slidably connected with the circular groove; The fixing column 2 is provided with a limiting component, and the limiting component is used to limit the pipe pile 12; The outer surface of the pipe pile 12 is provided with evenly arranged long grooves 13, and the long grooves 13 are long strips; the long grooves 13 cooperate with the limit assembly; In this embodiment, the limiting assembly includes a slide groove 21; The inner surface of the circular groove is provided with evenly arranged sliding grooves 21, and the sliding grooves 21 extend to the inside of the fixed column 2; the number of the sliding grooves 21 is the same as the number of the long grooves 13, and they correspond one to one; A limit plate 22 is slidably connected in each of the slide slots 21; a plurality of springs are fixedly connected to one side of each of the limit plates 22 away from the long slot 13, and the other side of the springs are fixedly connected in the slide slot 21; Each of the limit plates 22 extends into the corresponding long slot 13 in the initial state and is slidably connected with the long slot 13, and the spring is in an initial compression state in the initial state; Each of the two side end surfaces of the limiting plate 22 is provided with uniformly arranged first cylindrical grooves 23; each of the first cylindrical grooves 23 is slidably connected with a fixing rod 24; A spring is fixedly connected to each of the fixing rods 24, and the other side of the spring is connected to the first cylindrical slot 23; each of the first cylindrical slots 23 is initially located in the slide slot 21, and the fixing rod 24 is located in the first cylindrical slot 23 under the obstruction of the slide slot 21; In this embodiment, a slideway 25 is provided at the top and bottom of each of the limit plates 22 and inside the fixed column 2; Each of the slideways 25 is slidably connected with evenly arranged clamping plates 26; a side of each of the clamping plates 26 away from the limiting plate 22 is fixedly connected to a spring, and the other side of the spring is fixedly connected to the slideway 25; In the initial state, part of the clamping plate 26 intersects with the limiting plate 22, and the limiting plate 22 is limited and fixed; Specifically, during construction, a plurality of pipe piles 12 are first inserted into the bottom of the water in sequence according to design requirements, so that some of the pipe piles 12 are located above the water surface, and then the circular grooves on the fixed columns 2 on the floating body 11 are aligned with the pipe piles 12, and then the pipe piles 12 are passed through the circular grooves in the fixed columns 2. The floating body 11 will drive the fixed columns 2 to slide downward along the plurality of pipe piles 12 until they float on the water surface, and then the staff will install the substation 1 on the floating body 11 and connect it to the photovoltaic array on the water through cables; when the substation 1 is in use, the direct current generated by the photovoltaic array on the water is collected into the substation 1 through cables, and in the substation 1, the direct current is converted into alternating current after being stepped up by a step-up transformer, and then the alternating current is distributed to the output line through the power distribution equipment; More specifically, when waves appear on the water surface, the moving waves will act on the floating body 11. Since the floating body 11 is mounted on the multiple pipe piles 12 through the multiple fixed columns 2, the floating body 11 can be limited in the horizontal direction under the action of the multiple pipe piles 12, thereby preventing the floating body 11 from shaking back and forth in the horizontal direction when the waves act on the floating body 11. When the floating body 11 shakes due to the action of the waves, it can only move up and down along the pipe piles 12 by using the fixed columns 2, thereby preventing the floating body 11 from tilting or even drifting due to the action of the waves. At the same time, when the liquid level increases, the floating body 11 will drive the substation 1 to move upward with the rise of the liquid level, so that the substation 1 can adapt to the change of the water level, avoiding the substation 1 from being fixed in position. When the water level continues to rise, water will enter the substation 1. Furthermore, since the limiting plates 22 are inserted into the corresponding long grooves 13 on the pipe piles 12, when the floating body 11 floats up and down under the influence of waves, the fixed column 2 will drive the multiple limiting plates 22 to move up and down, and the limiting plates 22 that move up and down will move up and down along the long grooves 13, so that the fixed column 2 can be limited by inserting the limiting plates 22 into the long grooves 13. With the long-term use of the fixed column 2 and the pipe piles 12, since the fixed column 2 moves up and down along the pipe piles 12 for a long time, when the circular grooves in the pipe piles 12 and the fixed column 2 are worn, a gap will be generated between the pipe piles 12 and the circular grooves in the fixed column 2, A plurality of limit plates 22 are inserted into the long groove 13, and a plurality of clamping plates 26 are provided at the other end of the limit plates 22. In the initial state, some of the clamping plates 26 intersect with the limit plates 22, and the limit plates 22 are limited and fixed, so that the plurality of limit plates 22 can be limited in the corresponding long grooves 13, thereby limiting the fixed column 2, and preventing the floating body 11 from driving the fixed column 2 to collide with the pipe pile 12 when the floating body 11 is affected by waves, due to the gap between the pipe pile 12 and the circular groove of the fixed column 2, and when the limit fixation is not performed, the floating body 11 will cause the fixed column 2 to collide with the pipe pile 12, thereby causing the pipe pile 12 or the fixed column 2 to be deformed, thereby affecting the service life; Furthermore, when the limit plate 22 moves up and down along the long slot 13 for a long time, wear and tear will also occur between the limit plate 22 and the long slot 13. Since the limit plate 22 is fixedly connected to the compressed spring on the side away from the long slot 13, when there is a gap between the limit plate 22 and the long slot 13, the spring will push the limit plate 22 to move into the long slot 13, and the limit plate 22 will move in the slide slot 21. When the side of the limit plate 22 located in the long slot 13 is again in contact with the long slot 13, the limit plate 22 will no longer move. Since the first cylindrical slot 23 opened on the limit plate 22 is provided with a fixing rod 24, when the first cylindrical slot 23 on the limit plate 22 extends out of the slide slot 21, the fixing rod 24 in the first cylindrical slot 23 is pushed by the spring. The first and second clamping plates 26 are moved to the left and right sides of the first and second clamping plates 26 , respectively. By using the clamping plate 26 to limit the position of the limiting plate 22 in the corresponding long groove 13, when the pipe pile 12 after long-term wear and tear has a gap between the inner groove of the fixing column 2, the pipe pile 12 and the fixing column 2 can be limited by multiple limiting plates 22, so as to avoid that when the floating body 11 is affected by waves, due to the gap between the circular groove of the pipe pile 12 and the fixing column 2, and when the limiting fixation is not performed, the floating body 11 drives the fixing column 2 to hit the pipe pile 12, thereby causing the pipe pile 12 or The fixed column 2 will be deformed, which will affect its service life. At the same time, when there is a gap between the limit plate 22 and the long groove 13, the limit plate 22 will move into the long groove 13 and make the limit plate 22 fit with the long groove 13. Then, the limit plate 22 can be fixed by the extended fixing rod 24 and the clamping plate 26 intersecting with the limit plate 22, thereby preventing the limit plate 22 from sliding and being unable to limit and fix the fixed column 2, so that when the floating body 11 drives the fixed column 2 to move, it will hit the pipe pile 12.
[0019] Embodiment 2: Each of the limiting plates 22 is rotatably mounted with rollers 27 arranged evenly on one side close to the long slot 13; each of the rollers 27 rotates in the corresponding long slot 13; In this embodiment, each of the rollers 27 is unidirectionally rotatable, and the roller 27 can only rotate upward along the long slot 13; Each roller 27 is provided with tooth grooves 28 arranged evenly on its outer ring surface; the pile 12 is provided with second cylindrical grooves 3 arranged evenly, and the number of the second cylindrical grooves 3 is the same as the number of the long grooves 13 and corresponds to each other; the second cylindrical groove 3 is connected to the corresponding side of the long groove 13, and the roller 27 partially extends into the second cylindrical groove 3; A rotating rod 31 is rotatably connected in each of the second cylindrical slots 3, and a pipe pile 12 extends from the top of the rotating rod 31; The outer circumferential surface of each rotating rod 31 is fixedly connected with gear teeth 32 arranged evenly, and the gear teeth 32 are semicircular and slide in the second cylindrical groove 3; in the initial state, the gear teeth 32 correspond to the adjacent long grooves 13 and mesh with the tooth grooves 28 on the roller 27; One side of each rotating rod 31 extending out of the top of the pipe pile 12 is fixedly connected to the first gear 33; an equipment box is installed on the top of each pipe pile 12, and a first motor 34 is fixedly installed in the equipment box; The first motor 34 is provided with a second gear 35, and the second gear 35 is meshed with the plurality of first gears 33; the floating body 11 is provided with a wave sensor, and the wave sensor is used to monitor waves; Specifically, since one side of the limit plate 22 located in the long groove 13 is rotatably connected to the rollers 27 arranged evenly, when the fixed column 2 moves upward along the pipe pile 12, the rollers 27 will rotate in the long groove 13. In this process, it can be avoided that the limit plate 22 is fixed in the long groove 13, which causes the friction between the limit plate 22 and the long groove 13 to increase, thereby increasing the difficulty of the limit plate 22 moving upward along the long groove 13. More specifically, since the roller 27 partially extends into the second cylindrical groove 3, and a rotating rod 31 fixedly connected to the gear teeth 32 is provided in the second cylindrical groove 3, when the floating body 11 is affected by the waves and moves upward, the floating body 11 will drive the fixed column 2 to move upward, and the moving fixed column 2 will drive the roller 27 to move upward. Since the tooth groove 28 on the roller 27 is meshed with the gear teeth 32, the moving roller 27 will move upward while rotating along the gear teeth 32. When the fixed column 2 moves upward, since the roller 27 rotates unidirectionally, the moving fixed column 2 is connected to the gear teeth 32 and the roller 28 is meshed with the gear teeth 32. 27 is meshed with the tooth grooves 28 and no longer moves downward. Each time the wave pushes the floating body 11 and the fixed column 2 upward, the fixed column 2 and the floating body 11 after moving upward will be fixed. In this process, since the floating body 11 after moving upward is temporarily fixed, the impact of the wave on the floating body 11 will be reduced when the wave flows, and the frequency of the floating body 11 pushing the substation 1 up and down will be reduced, thereby avoiding the floating body 11 driving the substation 1 up and down for a long time, which will affect the normal operation of the equipment in the substation 1, and in serious cases, may cause equipment damage, short circuit and other safety accidents; Furthermore, if the wave sensor detects that the water surface tends to be calm, it controls the first motor 34 to rotate, the first motor 34 will drive the second gear 35 to rotate, the rotating second gear 35 will drive multiple first gears 33 to rotate, the first gear 33 will drive the rotating rod 31 to rotate in the second cylindrical groove 3, the rotating rotating rod 31 will drive the gear teeth 32 to rotate, when the rotating rod 31 drives the gear teeth 32 to rotate one hundred and eighty degrees, at this time the gear teeth 32 are no longer engaged with the tooth grooves 28 on the roller 27, then the floating body 11 will drive the fixed column 2 to slide downward under the action of gravity, when the floating body 11 floats to the water surface, the first motor 34 drives the rotating rod 31 to restore the initial state, so that the gear teeth 32 on the rotating rod 31 are engaged with the tooth grooves 28 again.
[0020] Embodiment 3: Two annular plates 4 are fixedly connected to the outer surface of the floating body 11; A rotating shaft arranged evenly is rotatably connected between the two annular plates 4; a rotating belt 41 is rotatably connected to the multiple rotating shafts; and a shifting plate 44 arranged evenly is fixedly connected to the outer ring surface of the rotating belt 41; In this embodiment, a second motor 42 is installed on the floating body 11; the second motor 42 is used to drive the rotating belt 41 to rotate; In this embodiment, the annular block 43 is above the annular plate 4; the bottom end surface of the annular block 43 is an arc surface; the top end surface of the annular block 43 is an inclined surface; Specifically, since the outer ring surface of the floating body 11 is rotatably connected to the rotating belt 41 through the rotating shaft, and the rotating belt 41 is fixedly connected to the shifting plate 44, when a wave passes on the water surface, it will push the rotating belt 41 to rotate along the floating body 11, and the rotating floating body 11 can change the direction of water flow, thereby partially removing the force of the wave on the floating body 11; More specifically, the second motor 42 can be controlled to rotate, and the rotating second motor 42 will drive the rotating belt 41 and the paddle to rotate, and the rotating paddle will move the water, so that ripples are formed on the water surface and spread with the floating body 11 as the center of the circle. When the spreading ripples meet the waves flowing toward the floating body 11, the ripples will offset part of the energy of the waves, thereby reducing the force of the waves hitting the floating body 11; Furthermore, since the bottom end surface of the annular block 43 is an arc surface, when a wave hits the floating body 11, the arc surface at the bottom of the annular block 43 can block the splashing water to prevent the splashing water from splashing onto the top of the floating body 11, thereby affecting the substation 1. At the same time, since the top end surface of the annular block 43 is an inclined surface, when water flows above the floating body 11, it will flow downward along the inclined surface on the annular block 43.
